ments in Gas-Producers. of which the following-1s a spcclfication- Thisinvention relates to the manufacture of producer gasand one of the objects there of is to provide a new"and improved producer. I

Another object is to provide apparatus of the above character. wherein the niass'will be kept from clogging and the formation of crevices and fissures prevented.

Another object, is to provide apparatus wherein producer gas of a' calorific quality will be generated.

Other objects will be in part obvious and in art pointed out hereinafter.-

he invention accordingly consists in features of construction. combinations of elements and arrangement of parts. which will be. exemplified in the construction hereinafter described, and the. scope of the application of which will be indicated in the following claims.

In the accompanying, drawings wherein is illustrated one of various embodiments of my invention: Figure 1 is a vertical. scctional view taken through the producer; Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1; and Fig. 3 is a similar view taken on the line 33 of Fig. 11

Similar reference characters refer to SllTlilar parts throughout theseveral views of the drawing.

Referring now to the dn'wiu zs A represents thebody of the producer the same bcing constituted, in the present instance. by upper and lower sections 2 and 3, respcctively, the upper section being supported as b)" means of legs 4 and struts The pro ducer is divided horizontallylo provide the upper and lower sections 2 and 3 along the line indicated at ti which construction per niits of the lower section 3 being revolved.

"This section is mounted upon a circular track T and has wheelsh adapted to traverse said track.

Thenieans provided for revolving section 3 comprises gear wheel mounted upon the shaft 11 driven by means of a pulley and belt 12 and 13 respectively. the latterreceiv-- ing its power from any suitable source. Gear wheel -1O meshes with peripheral teeth 1 -l carried externally of the revohible section.

In order to prevent the escape of gas from between sections 2 and 3 a water seal 15 is provided.

l6 denotes a basin or receptacle formed underneath the body of the producer into which depends a tapering end 17 of section The lower edge of the latter extends be low the level of the water in the basin whereby the lower end of the producer is chimedean screws 18 being provided for this purpose .in the presentembodiment of the invention. These. -screws may be revolved as by means of pulleys, 20 whereupon thescrews will deliver the ashes upon a traveling belt 21 which carries them from the producer.

Located centrally of the lower portion 17 of section 3 are twyer boxes 22. The twyer bdxes '22 radiate from a central box' 23 which 'receives the blast from a vertical portion 24 of a blast pipe 25 which extends upward-thmugh the lower end of the producer. 'lhe roofs of the twyer boxes are sloped as shown so that ashesin the lower portion of the producer will readil'y pom downward theretlirough. Located upon the ends of these twyer boxes is a. bracket '26 which has a curved portion 27 which when section is revolved will engage clinkers or other hard formations, thereby assisting in a prevention of clogging of the apparatus.

"8 cxteriorly of section Q-t of the blast pipe, said flange operating to feed ashes in a downward direction during the revolution of section 3.

The upper portion or section 9. of the roducer is provided with an arched mo 30 formed of bricks embedded in metal and formed centrally or the roofed portion is an aperture through which extends a revoluble chute 31. This chute is carried upon a shaft 39 extending upward centrally of the hopper 33 resting upon the roof portion 30 of the producer. the upper end of the shaft passing through the cover 34 of the hopper and having upon its upper end a bevel gear Meshing with bevel gear 35 a similar gear 36 upon horizontal shaft 3? supported in suitable journals 38 in a thereof;

bracket 39 carried by the hopper and this shaft has a second bevel gear id-thereon which. meshes with similar gear ll carried by the shaft 11. Shaft 11 is supported by means of a suitable thrust bearing 42 carried upon the bracket 4-3 mounted upon the up right i. Shaft 32 is provided with, a plurality of laterally extending members. 44 which. are positioned between radially extending members 45 upon the inner wall of ing therotation of shaft 32 to stir the fuel 1n the hopper and prevent any clogging plate 46 mounted'ina recess 4t? formed in hopper 33,- said plate coiiperating to support the s'haftgand, the appertures 48 of this plate are adapted to register'with corresponding apertures 5001 the plate car ried by the lower end of the hopper, hen

. these apertures are in registry the coal falls into chute 31 and when they are out of registry the chute is closed. A funnel 51 may be' employedfor'discharging fuel from the hopper and the damper 52 to close communication betweenthe funnel and the hopper.

Located within section 2 of the producer, in the present instance, is a depending annular'curtain or partition 53, the lower end of which terminates slightly above the point of jointure of sections2' and 3. The annular wall of this partition 01" curtain is spaced from the inner walls of section 2 of the producer to form a mixing chamber 54. The

partition 53 is supported at its lower endby- "means ofprojecting member 55 which extends laterally from the inner walls of section 2 ofvthe producer. Vertically extending members or webs 56 are provided between the exterior wall of the partition and the inner wall of section 2,said webs being in-' t'egrally or otherwise connected with said walls thereby forming an additional support for the partition. Partition 53 at its lower port-ion is provided with arched shaped recesses 57' so that gases passing downward therethrough may freely pass upward into the space provided between the exterior wall -.thereofand the inner. wallof section 2 of the producer.

The blast pipe 25 which, as shown, extends downward in a vertical direction adjacent the pmducer is provided with a branch 58 which leads into the space within the annular partition 53, said passageway being suitably valved as at 60. It will be understood that blast pipe :25 may be connected with a suitable source'of air supply or that. any other gas may be'discharged therethrough into theinterior of the producer.

61 and 62 respectively indicate. blowers or inspirators. The blower 61 being located preferably opposite branch pipe 58 and the blower 62 beinglocated near the lower end of the blast pipe which is provided with a Shaft 32 also. carries apertured eoneee Th e I blowers in the present instance are'of that class which are-actuated by a steamjet so that a proper admixture of steam and air may be discharged into the producer.

64 and 65 respectively indicate steam pipes which lead. into the blowers, said pipes being adapted to receivesteam from a feed pipe 66, in turn receiving its supply from a suitable source. Surrounding the annular the hopper. These members cooperate dur-..

partition 53 at its upper portion .is a correspondingly shaped space 67 from which leads a gas discharge conduit 68 Having thus described the construction of this embodiment of my invention the operation thereof, which to a large extent will be obvious is as follows: material in the present instance bituminous coal is introduced into the-hopper 53 anddischarged by chute 31 into the interiorv The carbonaceous of the producer, whence it falls into the combustion chamber constituted by the lower portion of section 3. The fuel is then lightedin thel'usua-l manner. l/Vhen a suit able bed of burning fuel has been obtained withinthe producer additional fresh fuelis introduced by means of the hopper and the apparatus is then ready to, operate. When -the apparatus is in normal operation the lower section 3 is revolved as has been heretofore explained, the'various dampers in the blast pipe being regulated to admit the proper amount of air or steam or an admixture of these gases into the interiorof the producer. The air or steam passing through the branch pipe 58 above the bed of fuel within the space interiorly of partition 53 which may be: termed retortll thenpasses .111 a. downward direction to meet the gases passing upward through the lower section 3 which may be termed a combustion cham- The gases thereupon pass upward through the space provided between the exterior wall of the partition and the inner wall of section2 of the producer which may be termed a mixing chamber. The gases arethen discharged from the producer by 'meansof the discharge conduit 68.

It will accordingly be seen that I have provided a construction well adapted, among others, to attain all the ends and objects of 1 my invention in a simple though eificient manner. As the fuel in the retort. becomes heated the more volatile hydroca-rbon constituent-s thereof are distilled off and these gases pass downwardly through a partly coked por tion of the fuel, then they pass around the, lower end of the partition 53 into the mixing chamber. These heavier hydrocarbon gases thereupon mix with the lighter and more permanent gases which pass upward through the bed of fuelin the lower part of the producer. It will be noted that the distillation and oxidation of the hydrocarbon constituents of the fuel will.

take place in the retort and that the coke will burned off in the lower portion thereof, sufficient oxygen being the blast to ox dize any volatile .terial unites largely-with the-t1'ee'carbon present to form carboninonoxid gas and any carbon .inonoxid gas formed [111 the lower portion of the producer of course will pass through the bed to the mixing chamber unchanged. 'Should it bedesired to coolthe mass or any porti0n-thereof or to furnish gas-rich with hydrogen, steam may be discharged from the twyer boxes into the lower section 3 0t theproducer and the hydrogen termed. by the disposition of the steam will of course passnnchangedf through the mass- Into the mixing chambe 1 I One lmporta-nt advantage attained by reasonof the present construction resides in the factthat the fuel beingjintreduced cool at the top of the. producer gradually heated beforearriving at the seat of c'onibustlon, and accordingly the loadmg of the apparas.

tus'witlrfuel does not affect the continuity ofthe generation of gas. Anotheriadvantage attained herein is the prevention of the lighter carbon gases from straining upward through the bed. meeting free air in theretortand'burning locally, thereby tending to ignite the heavier hydroi'rarbon gases and 'i.or.ming"combustion cavities in the body of the bed. Another in'iport'ant advantage accrui'ng herein is that the revolution of the lower portion of the producer tends to prevent any clogging or choking of the fuel within the producerand insures a steady progress of the mass from the time the fuel is introduced into the retort until the ashes are discharged from the lower end of the producer.

l of the producer, it will be obvious that its \Vhile I haveshownthe' depending curtain of annular form and dlsposed centrally shape may be changed or that it may be differently located within the producer.

As many changes could be made in the above construction and many apparently widely different eml'iotliments of this invenvti on could be made without departing from the scope thereof, it is intended that all matter contained in the above description or The carbon dioxid shown in the accompanying drawings shall be intcr n'eted as illustrative and not in a liniiting sense. It is also to be understood that the language used in the 'lollowing claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which as a matter of language, might be said to fall therebetwccn.

Having described my invention what I claim as new and desire to secure by Letters Patent is 'l. The combination in a gas producer of a casing comprising a fixed upper section and a revolublelower section, said upper ,seetlon having a depending annular curtain spaced from the walls thereof and terminating adjacent the point of jointure of said sections, means fordelivering a blast within said annular-curtain and also into the lower section of the producer-{and means for discharging gases :t'rom the space between said annular curtain. and the wall of said upper section.

2. The combination in a gasproducen'ot a casing comprising an upper fixed sectionand a lower movable section, a twyer box in the lower section, a support for said twyer box, and means on said support for forcing the ashes downward when the lower section is revolved.

twyer box having outstanding legs, means carried by said legs for engaging and crushing clinker-s or other hard Formations in the mass. a support For the twycr box, and means on said support which tends to force the ashes downward during the revolution of said lower section. V i

4. The combination in a gas producer. of a casing comprising upper and lower sections, a stationary twycr box in said lower sections, a support "for the twyer box, and a spiral arranged upon said support which is adapted to Force the ashes downward during the revolution of the twyer box.

In witness whereof I allix my signature in the presence of two witnesses.
